During 1925, young christian dior visited the "World Decorative Art Exhibition" while studying in Paris, which made him give up his studies and engage in artistic activities. He has established good relations with Matisse, Picasso and modern artists of the Paris School, and the activities of modern artists have influenced his future artistic direction. In 1950s, Dior followed the "new style" design and designed a series of women's dresses with new meanings and line of beauty. 1954 "h" fashion is simpler and younger than "New Style". Women's waists are no longer bound, and clothes no longer have so many useless details as before. 1955, he published "A" design and "Y" design, which became the most popular fashion design style in the West in the 1950s, and completely broke away from the "new style" that emphasized the design of the outer contour line, no longer pursuing the expression of curves, and turned to a relaxed, concise and comfortable style. From "new style" to "A" design, Dior's fashion focuses on elegant female beauty, which has always influenced the fashion design in Paris today.
